Remember how the FDA said there was “no evidence” that Chinese toothpaste tainted with diethylene glycol had made it to the U.S.? That was wrong.

The FDA is now warning that there is a “low but meaningful risk of toxicity and injury” to people who use the following brands of discount toothpaste: Cooldent Fluoride, Cooldent Spearmint, Cooldent ICE, Dr. Cool, Superdent, Clean Rite, Oralmax Extreme, Oral Bright, Bright Max, and ShiR Fresh Mint.

The tainted toothpaste has been spotted at bargain stores in Los Angeles, Miami, and Puerto Rico. The FDA has devised a simple test to evaluate the safety of your toothpaste: if it says “Made in China,” throw it out. — CAREY GREENBERG-BERGER
